That’s a great idea…

grinding the dried Grifola into powder and adding to things like meatballs, adding an extra binding element… not to mention that the flavor and nutrition are enhanced. I use old blown-out King Bolete tubes like this. Always good to learn a new way to use the oft-abundant Grifola.

dehydrating nicely

I kept the Gymnopilus in dehydrator overnight..almost “done”..looking very good like the dried shitake you buy in the grocery….

I grind the dried Grifola into a powder to use in cooking…I’ve added it to turkey meatballs which came out nicely and I plan to try making acorn bacon….I harvest the acorn starch when making acorn flour which has a gooey consistency…will try mixing the Grifola powder with acorn starch and a ton of salt and maple syrup… daughter found a youtube video on making it!

A few of my MO observations…

for Gymnopilus… obs 111688, obs 114608. These are ones where the argument seems to center around junonius vs. subspectabilis vs. validipes. The mushrooms are all yellowish (not orange). Note how the voting on the ID proposals shows that there is a lack of agreement on how to name the robust caespitose ones. This is the source of my own confusion regarding the application of species names within this group.

The ones seen here in crumpybumpy’s observation are not the same as the ones seen via the links to my observations (above).

Because I am used to seeing a more vibrant color on G. luteus, the other names came to mind. As mentioned, the color here is not adequately represented in the photos. These lack the really thick/robust stipes of subspectabilis. Also, it appears the cap surface of subspectabilis tends to break apart into patches, something not seen here.

Thanks for providing the impetus for my review of the large Gymnopilis taxa. I agree, the name that best applies here is luteus.

Orange ?

Dave my brother, not sure what are you on about here. This collection clearly represents G.luteus. They are all variably orange in that group. Some of us frequenting psychoactive mushroom identification websites see a lot of those species, and we can tell them apart with ease.
You have comparison shots posted recently on MO by user Huafang, and you have many other collections on MO to compare those two. If you do that, I’m sure till the end of the day you will start recognizing them.


Different sources…

differently emphasize the the relative orange vs. yellowish color of G. luteus vs. G. junonius/subspectabilis. Measuring spores appears to be the only way to differentiate. And even then, if the lengths of spores seen are all in the 8-9 micron range, then…?

Different types of fungi seem to require different numbers of hours in a dehydrator. Properly dried material should not be at all flexible. How do you use dried Grifola?

these were definitely vivid orange and drying question

These pics I don’t think fully demonstrate how orange these are….When I passed the stump I first thought at first omphalotus illudens due to how orange…and also Galerina marginata orange….I am going back today to collect specimens for drying and further study…when I dry them…how much do I dry them? I’ve used my dehydrator for maitake but I think I overdo it as there is almost nothing left!

Looking at the C du Q…

documentation of G. luteus and G. subspectabilis, I don’t see many consistent morphological differences. Within the C du Q comments under G. subspectabilis microscopic details are offered as the way to make the distinction.

In my experience what I nhave IDed as G. luteus is usually more vividly orange and the partial veil more apt to collapse as “ring zone” on the stipe. Lighter-colored specimens with more abruptly clavate stipe are what I had called “junonius” in the past. My understanding is these are what are now called “subspectabilis” in eastern NA.

What Mushroom Expert calls “Gymnopilus junonius” I believe is now called G. subspectabilis (in NA). The persistent annulus with downturned aspect (seen in the last, ie. 6th, photo) matches what ME says about “G. junonius”.
